Fixed Undefined activityDescription


Well-known member
Just got this clicking on a logged in user:
Undefined index: activityDescription
  1. XenForo_Application::handlePhpError() in XenForo/Model/Session.php at line 372
  2. XenForo_Model_Session->getSessionActivityDetails() in XenForo/ControllerPublic/Member.php at line 816
  3. XenForo_ControllerPublic_Member->actionCard() in XenForo/FrontController.php at line 310
  4. XenForo_FrontController->dispatch() in XenForo/FrontController.php at line 132
  5. XenForo_FrontController->run() in /data/websites/ at line 13
Other users are working fine.

I'm not sure how to reproduce that (add-on related?), and unfortunately the error doesn't give me a lot of details, but I've prevented this error.
